Definitions

  • the present invention relates to a minimally invasive implant for the purpose of opening between spinous processes, and more particularly to an interspinous spacer for expanding a spinal canal.
  • the spinal canal is a longitudinal cylindrical space in the center of the spine (vertebra), in which the spinal cord and the tail (nerve) are contained and firmly protected.
  • Spinal canal stenosis in which the spinal canal is narrowed due to various causes such as deformation of bone, cartilage, ligaments, etc., and the nerves inside it are compressed, the number of patients is increasing with the aging society. It is an increasing social issue
  • lumbar spinal canal stenosis is caused by deformity and thickening of the lumbar intervertebral joints, degeneration and swelling of the intervertebral disc that is soft tissue, and thickening of the ligaments.
  • Symptoms are typically gait disturbances such as neurological intermittent claudication, which is characterized by the fact that the lower limbs do not appear forward after walking for about a few minutes, and that they can walk again after crouching for a while. .
  • Lumbar spinal canal stenosis is known to be anatomically reduced and symptomatically reduced by bending the lumbar spine by squatting or riding a bicycle.
  • Conservative treatment methods include drug therapy that administers drugs that increase vascular dilation or blood flow around the nerve root or tail, and dura mater.
  • ultrasonic therapy to improve analgesia, muscle spasticity, and blood circulation 'hot pack'
  • There is physical therapy such as therapy.
  • surgical therapies to counter this conservative treatment, such as laminectomy and enlarged fenestration. Neural decompression was a technique that has been used in the past.
  • Laminectomy and enlarged fenestration techniques require the patient to undergo general anesthesia because of the surgical invasion of the patient to repair the lumbar stenosis. This technique can also put patients at risk of bleeding and serious complications and requires hospitalization in the ward for days to weeks after surgery. Therefore, this technique can further exacerbate the symptoms, especially when the patient is elderly and the patient is elderly.

Since the cost of treatment can be lower, it is desirable to be able to treat spinal stenosis using minimally invasive procedures.

Abstract

L’invention propose de réaliser un procédé de thérapie très peu invasive de sténose de canal spinal à l’aide d’un dispositif thérapeutique capable de placer de manière stationnaire une entretoise interspinale sans faire appel à une grande incision cutanée ni une incision des tissus ligamenteux et également sans devoir détacher le muscle paraspinal de la colonne vertébrale. Elle concerne alors une entretoise interspinale comprenant une zone de vis conoïde (2) à visser dans un espace d’apophyse épineuse; une zone d’entretoise (3) disposée dans la direction longitudinale de la zone de vis (2) ; une zone de tête (4) capable de se solidariser librement avec un outil de façon arbitraire ; et un trou traversant (5) passant par le centre axial de la zone de vis (2), de la zone d’entretoise (3) et de la zone de tête (4). L’espace d’apophyse épineuse peut être agrandi en douceur en vissant la zone de vis (2) dans l’espace d’apophyse épineuse. La zone d’entretoise (3) se trouve pincée lors du passage de la zone de vis (2) à travers l’espace d’apophyse épineuse pour ainsi agrandir et fixer les espaces d’apophyse épineuse adjacents. L’entretoise interspinale peut être guidée vers une position interspinale par insertion d’un élément de guidage dans le trou traversant (5) aménagé le long du centre axial de la zone de vis (2) et de la zone d’entretoise (3) et par pénétration dans le corps le long de l’élément de guidage.
